The sum of three positive integers is 42. The smallest integer is five less than the middle integer. The middle integer is three less than half the greatest integer. Define a variable, write an equation and solve to find the three integers.
Form an equation, but with what? You'll need variables, so make them! (Here is a lovely recipe for variables)
Let:
s = smallest number
m = middle number
l = largest number
But...you can't just add that!
Let's write everything in terms of "m".
s = m - 5
m = m
l = 2m + 3
Now...we add!
m - 5 + m + 2m + 3 = 42
4m - 2 = 42
4m = 44
m = 11
Now, we plug m back into the original variables:
s = 11 - 5 = 6
l = 2(11) + 3 = 25
So, the 3 numbers are [6, 11, 25]
Did you actually press on the link? No recipe? Just a definition? Sorry...have some cookies! (They are up at the top shelf of my pantry...they taste nice, but not as good as Ginger's banana daiquiri! I managed to sneak a sip...hope she doesn't realize!)
